The purpose of this study was to obtain information regarding the speciation of cadmium (Cd), lead (Pb), and copper (Cu) in an estuary area. Only the distribution of metal in the soluble fraction (size smaller than 0.45 pm) will be investigated in this paper. The Seine estuary was chosen in order to study the effects of estuarine processes on the behaviour of metals and organic-matter carried by rivers discharging into very high tides (such tides produce considerable water displacement). 

The results for the Seine estuary samples are shown in Table 1. Column (A) corresponds to ionic species , column (C) corresponds to. the total amount of metal, (B)—(A) is the weakly bonded species, and (C)—(B) the stron y bonded ones. Significant amounts of dissolved non4abile metal are obtained for almost all samples, indicating that a simple acidification does not release all the metal... 

For equilibrium computer calculations, 48 species were considered. The distribution of Cd, Pb, and Cu — for natural pH — in the Seine estuary are summarised in Table 4 (species accounting for less than 1% of the total metal were disregarded). It should be pointed out that these speciation results are very dependent upon the values which...

In the Seine estuary, the trace metal speciation is quite similar to the theoretical one of Mantoura and Coll. [15 ] except for Cu. For this last metal, our results are in good agreement with those of Van den Berg[9]for the Irish Sea. 

Phenols derived from lignin degradation were used as markers to determine the origin of waters of the Seine estuary in France. Thus, fluvial run-off contains syringic, hydroxyben-zoic and vanillic phenols, whereas upstream penetrating marine waters contain cinnamic phenols derived from the estuarine herbs. In the maximum turbidity zone the vanillic acid (38) to vanillin (39) ratio increases due to aerobic degradation of lignin . ... 

Waters from wetlands and lakes may have relatively high concentrations of NOM. A study of surface water quality of wetland has been carried out on one of the Seine estuary, the Hode Marsh. This littoral wetland is located on the northern part of the Seine floodplain in France. 

The quality of a peatland and its environment has been studied [25]. The Grand Mare (sampling stations 4 and 5) is a peatland of 47 ha, located in a wetland of the Seine estuary, the Vernier Marsh. Since it is the lowest part of the marsh, all annexes converge in it le Ruel (sampling station 1), Petite Mare (sampling station 2) and la Crevasse...

De Voogt et al. [23] analysed marine and estuarine sediments from 22 sites in northwestern Europe (extending from Ireland and France to Norway and Sweden) by HPLC-FL. NP, OP, AgPEO and AgPEO concentration ranges of 0.1-17, highest levels were found in the estuaries of the rivers Seine, Mersey, Rhine/Meuse, Weser and Elbe.
